Regarding 9mm, last summer I was in my house and heard a loud BANG! Went to the window to see a neighbor two houses over pop up from a different neighbor's deck like a sniper and fire several more shots from what appeared to be a carbine rifle. This was a residential area. I knew he was going after a groundhog. Then he came off the deck, disappeared into his overgrown jungle of a garden and I heard a few more shots.
Talking with my immediate next door neighbor, the guy was using a camp 9 and took over 5 shots to put the groundhog down. That probably isn't the 9mm round's fault; the guy is an idiot.
A couple weeks ago I hear shots and look out the window to see a different squirrely neighbor shooting a possum at point blank range... again and again and again, and the poor thing got up and walked away. Again, talking to my next door neighbor, she was using a 9mm, and ran out of ammo. He had to put it down with a .22. And, again, it wasn't the 9mm's fault. It was the nutjob neighbor.
However, it brings up the question of humanely killing a groundhog. 9mm shot from a pistol at 50 yards, for most folks, isn't going to put it down immediately. So if you do that, please run up there and put the poor thing out of its misery ASAP.
